Application filed 'Iebruary 23, 1905. flerial No. 247,007.,

In on whom, it may concern: :Be it known that I, CHARLES CLARENCE ,OOLE, a citizen of the United States, residing atEvan'ston, in the county of Oookand State of Illinois, have invented certain new and useful Improvements in Paper-Move ment Indicators for Type-Writers, and I do hereby declare that the following is a full, clear, and exact.description'thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification. 1

This invention relates to a novel indicator for use on'paper-carriages of type writing machines, and designed to indicate the extent to which the platen shouldbe turned backwardly by hand for inserting new sheets when making carbon copies .of a number ofwriti ings on a single record strip or sheet and with unlfor'm or predetermined spaces between such carbon copies, a,

The invention consists in the matters heie inafter set forth, and more ed out in the appended claims.

In the accompanyin drawin s, Figure 1 is .a perspective v1ew oft e right-hand end of a paper-carriage, showing: the platen therein and my improved indicator applied thereto. Fig. 2 is an end view of the carriage with the Fig. '3 is a secparts constituting the inplaneaxially of the platentional view of the vention, taken in a Shaft As shown in the drawings, A designates the platen or paper-roller; B, the right-hand end plate of the paper-carriage,in which the shaft a of the platen has bearin Cand D, paperguides on the carriage E, he upper longitudinal frame-bar of the carriage; F, one of the paper-guides mounted onsaid-frame-bar; G,

the upper guide-roller of the carria e, an d H the scale-strip located above the platen and adjacent to the guide-roller.

A designates the right-hand turning-knob of the platen-shaft, which is aflixed to the t shaft by a short sleeve a, that fits over and is attached to the end of said shaft.

The arts above described correspond with those ound in the Oliver type-writing machine, in which the typelevers are located above the platen and the types strike down wardly upon the platen-surface.

I designates a rotative part mounted on the shown,

particularly pointcessed to receive the collar M. normally locked to the platen-shaft, so that shaft a of the platen and having, as herein the general form of a disk. It car- Ii'es an index-finger or pointer J, which is mounted on the patc -shaft and is adapted to turn with said shaft and also to be turned by handon the shaft. Said disk is herein shown as provided with circumferentiallyspaced graduations or scale-marks which are spaced at uniform angular distances apart to correspond with the line-space movement of theplaten and are progressively numbered from the index-hand or pointer J of the disk, said index or pointer being located at and constituting the zero-point of the scale.

K designates an index-fingeror ointeron the carriage-frame, which coabts with the indeX-finger J on the disk I.

L designates an index finger or pointer which is mounted on and turns with the disk I and is adapted'also to be turned or rotated about the shaft angularly toward and from the index-finger J, andthereby adjusted in varying angular positions with respect to said finger J.

platen-shaft, so as to turn therewith during the usual line-sp acing movement of the platen,

'the locking device being so constructed as to permit the disk to be turned or angularly shifted onthe shaft by hand when desired for the purpose of setting the indicator preparatory to introducing intdthe machine.

a new sheet of paper The pointer L may be connected with the disk I in any suitable manner'adapted to retain the same in any positonto which it may be adjusted with-re spect to the pointer J on the disk, while en 'abling the pointer L to be angularly shifted when desired with respect to the pointer J.

Referring now to the details of construction of the features above referred to and as illustrated herein, they are made as follows: The disk or rotative part I is mounted on the platen-shaft-c outside of the adjacent end plate B. Said disk is provided on its outer face with an elongated axial hub I,in which the shaft a has bearing. The inner face of the disk bears against a collar M, mounted in and fixed to the platen-shaft by means of a set-screw m, by which inward movement of the (lisk'on the shaft is limited. In the present instance the inner face. of the disk is re- The disk I is The disk I is adapted to be locked to the during the usual writing operation of the machine the said disk and the parts carried thereby rotate with the platen. According to the present invention said disk is positively locked to the platen-shaft by means of a suitable clutch device, which must be released in order to permit the disk to rotate on said shaft. Referring now to the construction whereby said disk is locked to the platenshaft and is released therefrom to permit it to be turned on the platen-shaft,said parts are made as follows: N designates a clutch-sleeve surrounding the platen-shaft between the disk and the sleeve (1/ of the turning-knob. Said sleeve is provided with a reduced bearing portion 11, that has bearing directly on the shaft, and with a larger inner end at, that fits over the adjacent end of the hub I ofothe disk I. The adjacent ends of the clutchsleeve and the knob-sleeve a, are provided with clutch-teeth, which serve to lock said clutch-sleeve to the platen-shaft. Said sleeve N is free to slide endwise on the platenshaft, but is non-rotative relatively to the hub of the disk I, whereby when the clutchteeth are engaged and the platen-shaft is rotated the said clutch-sleeve and disk are likewise rotated. The non-rotative endwiseshifting connection between the sleeve N and the hub of the disk is afforded in the present instance by means of a pin or stud n extending radially through the larger end of the sleeve N and engaging a short slot i, formed in the hub of the disk. The clutch members are held normally engaged by means of a spiral eXpansively-acting spring 0, surrounding the shaft within the larger part of said sleeve and interposed between the end of the diskhub and the annular shoulder formed between the larger and smaller parts of said sleeve. Said spring also serves to hold the disk against the collar M. When it is desired, therefore, to rotate the disk on the platenshaft, the clutch is released by forcing the clutch-sleeve inwardly against the action of the spring 0 and while still holding the sleeve inwardly rotating the sleeve and disk to the desired point. When the sleeve is released, the spring acts to force the clutch-teeth into engagement and lock the disk to the shaft. In order to facilitate the manipulation of the clutch-sleeve described, it is shown as provided with a flange N, which may be readily grasped by the fingers.

The pointer L, which is mounted on and turns with the disk I, is in the construction illustrated in the drawings attached to a radial arm L; secured to an annular member having the form of a hub or sleeve L, which is mounted on and is adapted to rotate about the disk-hub I. The said hub or sleeve L is held from endwise movement on the diskhub by a ring '1'", which surrounds the outer end of the disk-hub and is secured thereto by means of a screw The locking device for holding the pointer in an adjusted position with respect to the pointer or indicator J on the disk I consists, as shown in the drawings, of a spring-actuated locking-detent P, mounted in the arm and adapted to engage one of a series of circumfercntially-disposed locking holes or recesses Q Q, formed in the outer face of the disk I. Said locking-detent P has the form of sliding pin mounted in a cylindric casing Z on the arm L, and said pin is held normally engaged with one of the locking-recesses by a coiled spring Z, that surrounds the detent-pin within the casing l. Said spring bears at one end against an inwardly-facing annular shoulder at the outer end of the casing and is connected at its opposite end with the detent-pin in a manner to transmit endwise movement thereto. The detent P is provided at its outer end with a head or knob p, by which it may be drawn outwardly by the fingers to release it from the recess Q preparatory to adjusting the pointer L relatively to the pointer J. The indicating-disk is preferably provided with a cylindric peripheral surface on which is formed the graduations or scale-marks referred to, so that said graduations and the numbers applied thereto may be readily observed by the operator. In connection with the scale so marked on the disk I the stationarypointer K is extended horizontally from the end of the carriage over the inner edge of the peripheral surface of said disk and the pointer L extends at right angles from its sup orting-arm inwardly over said cylindric sur ace.

The operation of the indicating device described will be understood from the following The general purpose of said paper-move: ment-indicating device is to indicate to the operator the extent of angular movement of the platen required when inserting a sheet of paper into the machine in order to bring the first line of printing a desired distance from the top margin of the paper according to the space occupied by the heading on the sheet. More particularly the indicating de vice is designed for use in cases where it is desired to make out a number of bills or invoicesand to make carbon copies of the same on a single strip or long sheet of paper. In a case of this kind it is desirable that the copies should be spaced as closely as possible on the record-strip, but at a uniform distance apart, or with equal spaces between the several records or copies, and the line-indicating device herein shown is employed to readily insert a new sheet for each separate original bill or invoice which has been removed from the machine in such manner that the first printed line of the carbon copy shall be located at a desired distance from the last printed line of the preceding carbon copy, while insuring that the first line of the original bill or invoice will come with certainty in proper position with respect to the top margin of the sheet on which said original bill or invoice is printed. For instance, assuming and the platen then turned backwardly to move or shift the record-strip backwardly to such a point that when a new sheet is inserted the part of the new sheet on which the first line is to be printed will be located at such distance from the last line of the carbon copy a as to leave a desired space between the copies.

In-using the indicating device described the operator sets the pointer L at a distance from the poi'nterJ equal to the distance which it is necessary to turn the platen backwardly after printing the last line of one bill or invoice in order to start a new original sheet in the machine in such manner that the first line of the next bill or invoice when started at the proper place on the original sheet will on the copy-sheet come at a desired distance 'of two, three, or more lines from the last line of the preceding carbon copy. This may be done as follows: When the last line of the first bill or invoice has been completed, the

operator turns the disk I so as to bring the. pointer J opposite the fixed pointer K. He then turns the platen backwardly (the disk turning with the platen) until the platen reaches a proper position for the insertion of a new sheet, allowance being made for the" desired space between the firstand-suc'ceeding carbon copy. .Such movement of the first original and carbon-sheets is effected wlnle the original sheet is in place in order to determine the extent of the backward movement'required to enable the printing to be started on the next succeeding original bill with the proper space between the copies on the carbon strip. The laten is now allowed to remain in the position last indicated and the pointer L is turnedon the disk 'I until it is brought opposite to the fixed pointer K. The angular distance between the pointers J andLwill now correspond with and indicates the distance which the platen 'must be turned backwardly after the printing of each original sheet to bring the copy of the. next blank original sheet at the desired distance from the copy of the preceding original sheet and at the same time afi'ords the desired spacing between the copies of the carbon-sheet.

In the use of thedevice imprinting after the pointer L the manner described or otherwise the printhas once been adjusted to a, "fixed positlon relatively to the pointer J in ing of each invoice, having a like width of heading as the first invoice referred to, is completed in the usual manneryand on the completion of the last linethereof, or after the printed original has been removed, the disk I Is released from the platen-shaft and turned thereon without turning the platen until such pointer J is opposite the stationary pointer K. The platen is then turned backwardly, carrying with it the disk I and pointers J and L,

until the pointer L is opposite to the stationary pointer K. The new sheet of paper 's then inserted by being thrust into themachine in the usual manner, and the platen is thereafter turned forwardly to carry the record-sheet and the new original sheet into position for printing, which position is determined by the new original sheet.

It follows that by the use of the device described the operator, having once determinedthe angular distance'for a number of linespaces which the platen must be turned back wardly for starting a new sheet, can in each instance or when inserting each new original sheet for an original bill or invoice invariably turn the platen backwardly to the same distance according to the angular distance between the pointers J and L, and will thus be enabled to invariably bring the first printed line of the carbon copy the same distance from the last printed line of the previouslymade copy rbn said record-sheet, thereby leaving uniform spaces between the several carbon copies of the record-sheet. Moreover, the operator is enabled to locate the carbon copies on the record-sheet as closely together as desirable-without danger, on the one hand, of bringing together or overlapping said carbon copies and without liability, on

on the other hand, of separating the carbon copies on the record-sheet so widely as to cause an objectionable wastage ofpaperon the carbon and record sheets.

The graduations or scale marks on the disk I ar mainly useful to enable the pointer Lto be adjusted to a desired position for original sheets having headings of difie'rent wid ths without any test to determine such positions when the operator has previously ascertained and knows from recollection the spaces on the scale at which the pointer must be located for the different original sheets. Moreover, as the graduations correspond with the line-spaces if the operator desires to make the space between carbon copies greater or less this can be done by merely shifting the pointer L backwardly or forwardly by one or more spaces, as desired. It will be observed, therefore, that the. graduations on the disk I have no function to perform in the usual op eration of the disk or wheel, the only parts coming into use at such time being the ointer K on the frame and the fixed and ads able pointers on the disk, the angular distance 1 of which latter from each other determines ustthe distance through which the platen is to be turned. backwardly in inserting each new sheet.

While the disk I is shown as having a projecting part forming the pointer J, yet the same result will be attained by providing said disk with a score-line or zero-mark for the scale. Moreover, the stationary pointer K may be replaced by a mark or score-line on the end plate of the carriage-frame.

From what has been heretofore stated it will be understood that the term pointer as used in the appended claims is intended to mean as well a disk provided with an indicating-mark or score-line or a part of or upon the carriage-frame having such mark or scoreline, as a projecting part, arm, or indexfinger, the parts referred to in either case equally performing the functions of an indicating means to determine the line-space position of the platen or the extent to which it is turned.
